 your comment on the $fis->addRule, I am not sure if I understood it. Could you, please, rephrase it? the following chunk of code: class='codeblock'>$fis->addRule( &   speed=slow'       =>  'award=minimum', &   speed=slow'       =>  'award=minimum', &   speed=slow'       =>  'award=small', &   speed=slow'       =>  'award=small', &   speed=regular'    =>  'award=minimum', &   speed=regular'    =>  'award=small', &   speed=regular'    =>  'award=small', &   speed=regular'    =>  'award=excellent', &   speed=fast'       =>  'award=small', &   speed=fast'       =>  'award=good', &   speed=fast'       =>  'award=good', &   speed=fast'       =>  'award=excellent', &   speed=fastest'    =>  'award=small', &   speed=fastest'    =>  'award=good', &   speed=fastest'    =>  'award=excellent', &   speed=fastest'    =>  'award=excellent', class='embed-code-dl'>[download]

if that could be replaced with just an array (in my original post), for prevention of errors and maintainability. Just a thought.

Hi talexb, Now, I got it! It will be hard to change that particular chunk of code for an array because of the way those statements are treated in the AI::FuzzyInference module (please, see the code below). However, I will think about your idea and see if I can suggest some improvements to the module thank you lin0 `# sub addRule() - public method. # # Adds fuzzy if-then inference rules. # # $obj->addRule('x=medium' => 'z = slow', # 'x=low & y=small' => 'z = fast', # 'x=high & y=tiny' => 'z=veryfast'); # spaces are optional. The characters [&=\|] are special. sub addRule { my ($self, %rules) = @_; for my $k (keys %rules) { my $v = $rules{$k}; s/\s+//g for $v, $k; push @{$self->{RULES}} => [$k, $v]; } return 1; }` [download]	[reply] [d/l]

sub addRule {

    push @{$self->{RULES}} => [$k, $v];
    }

    return 1;
